Study of life-threatening infections to find genetic causes
This trial studies people who have had a life-threatening infection to look for genetic reasons why some infections are so severe. If you or a child had a serious infection—like severe flu, meningitis, or a deep abscess—that could not be explained by a weak immune system from other causes, this study may help find answers.

DNA test to guide antibiotic use for pneumonia in ICU patients
This study tests whether using a DNA test on lung fluid can help doctors choose better antibiotics for pneumonia in ICU patients with weakened immune systems. It may lead to more effective treatment and fewer side effects.
LilleAges 18 years+ - NCT06860542RecruitingPhase 2
Inhaled steroid to prevent lung inflammation from returning after immunotherapy
This trial tests whether using an inhaled steroid (budesonide) can help prevent lung inflammation (pneumonitis) from coming back in people who have had it caused by immunotherapy cancer treatment. It may be an option for patients who need extra support after their first bout of this side effect.
